• Summary List (Last 1 Hour)—This list provides per second traffic rate summarized by host traffic
analysis task. This list provides navigation to more detailed host reporting for the selected task.
Host traffic analysis configuration considerations
The following information explains configuration considerations and how to maximize the NTA host
reporting features. There are several things to consider when you add hosts to a task, the most important
of which is how you select the hosts that belong to each task. Additional considerations follow:
• By default, NTA does not monitor any hosts. You must create a task for every host or group of hosts
on which you want to monitor and report.
• You must enable network flow data on the devices and for the interfaces on them for those locations
on your network where you know host traffic for can be captured. Then, you must add these devices
and probes to NTA using the features described in " Device management " and " Probe
management ." NTA then summarizes application data for all devices and probes on which it
observes the application traffic.
• NTA provides summarized host reporting based on the way you have grouped hosts into tasks.
Consider how you want to summarize, access, and view host data. Then, structure your tasks
around it. For example, you can create a host task called NetMgmtHosts and add all of the hosts
used in your environment that support network management. NTA summarizes all traffic observed
for all hosts into the group NetMgmtHosts and attribute traffic in the reports to the task name you
have configured.
Managing host traffic analysis tasks
NTA processes, analyzes, and reports on network flow data through the tasks that administrators create.
Until you create a task, NTA does not analyze the data that devices forward to it or that it is configured
to receive. Effective management of tasks results in the reporting you need. The following information
describes the process for adding, modifying, or removing host traffic analysis tasks in NTA.
Viewing a traffic analysis task
NTA displays all traffic analysis tasks in the Traffic Analysis Task List.
To view the NTA traffic analysis task list:
1. Select Service > Traffic Analysis and Audit > Settings.
2. In the Settings area of the Traffic Analysis and Audit page, click the Traffic Analysis Task
Management link.
NTA displays all tasks in the Traffic Analysis Task List in the main pane of the Task Management
page.

• Task Name—Contains the name of the task. The contents of this field link to the Traffic
Analysis Task Details page for the associated task.
• Task Description—Contains the description for the associated task.
